Worth every penny
Considering how horribly wrong things can go when an o-ring fails, and given how difficult they can be to find when that moment occurs, having a kit like this on hand is invaluable. The o-rings in this kit appear to be well made and they've all held up perfectly well since install. Having plenty of extras is great peace of mind.
